The utility model discloses a temperature early warning device applied to a machine room. The temperature early warning device comprises a graphene-based sensitive material coating, a hollow substrate, a signal amplifier, an electric wire, a safety resistor, a comparator and an alarm. The graphene-based sensitive material coating is flatly laid on a first plane of the hollow substrate, the signal amplifier is connected with the safety resistor and arranged in the hollow substrate, and the connecting wire is connected with the signal amplifier and the safety resistor in the hollow substrate through small holes preset in the side face of the first plane. One end of the comparator is connected with the signal amplifier and the safety resistor in the hollow substrate through the small hole, and the other end of the comparator is connected with the alarm. The temperature early-warning device is simple in structure and reasonable in design, the temperature early-warning function can be achieved only by placing the
